Tricyclic antidepressants are more effective than SSRIs in the treatment of neuropathic pain syndromes.Antiepileptic drugs act at several sites that may be relevant to pain, but the precise mechanism of their analgesic effect remains unclear.These agents are thought to limit neuronal excitation and enhance inhibition.Tricyclic antidepressants have documented (although limited) efficacy in the treatment of fibromyalgia and chronic low back pain.Recent evidence suggests that duloxetine and pregabalin have modest efficacy in patients with fibromyalgia.Transmission of painful stimuli through the spinal column and CNS is modulated by excitatory and inhibitory neurotransmitters, as well as actions at sodium and calcium channels.

Norepinephrine and serotonin may be excitatory or inhibitory, but they are functionally inhibitory on pain transmission; glutamate is the other important excitatory neurotransmitter.An estimated 2.6 patients must be treated with tricyclic antidepressants and 6.7 patients with SSRIs to have one patient with more than 50 percent pain relief.Serotoninergic antidepressants and currently approved antiepileptic drugs have little documented efficacy and therefore should not be used as first-line medications in the treatment of non-neuropathic pain.In addition, histamine H-receptor affinity (associated with sedation) may be correlated with the analgesic effect of antidepressants.Amitriptyline (Elavil) also has an analgesic effect in patients with acute pain.4Tricyclic antidepressants may be categorized as secondary or tertiary amines.The actions of antidepressants and antiepileptic drugs differ in neuropathic and non-neuropathic pain, and agents within each medication class have varying degrees of efficacy.
